Yeah they didn't market it as the third game in a series but I wonder who cares about how they market their game lol You don't need to know the universe or the characters to enjoy it so I don't see a problem with their approach, I'm actually glad that they are successful with it.

Witcher 1 was pretty obscure, but Witcher 2 was pretty well known because it came out of nowhere and was so good. Witcher 3 got a ton of traction, especially since they spent $25 mill on advertising it.
